This invention relates to certain new and useful improvements in vending machines,

andmore particularly pertains to a device for use with vending machines whereby nickels and dimes can be used to operate the machine, and wherein the device can be ad justed so as to require different sums of money to operate same. In other words the invention aims to enable the machine to be set so as to permit operation thereof by means of various-sums for example, 5, 10, 15, 20, 25 cents, etc. In the drawings Figure 1 is a side elevation of the invention, partly in section, Figure 2 is a fragmentary top plan view, Figure 3 is a section on line 3.3 of Figure Figure 4 is a'section on line 4-4 of Figure 2, a 0 Figure 5 is .a detail perspective view of the coin engaging pusher.

In proceeding in accordance with the present invention, a casing 1 is employed having a top 2 formed with coin slots 3 and 4, the

latter slot beingfor use with dimes while i the slot 3 is for use with nickels.

A vertically disposed rod '5 is slidable through the top 2 and through a member 6 disposed below the top, the rod having a hand engaging knob 7 on its upper end. The coin slots 3 and 4 register with the usual coin chutes provided therefor in thecasing. A coin engaging pusher 8 of substantially L-shape as s own in Figure 5 is provided with an openin 9 to slidably receive the rod 5, and is furt er formed with outwardly projecting feet 10 which latter roject within the respective coin chutes. coil spring 11 surrounds the rod 5 and exerts pressure 40. against the top of the coin pusher 8, holding the latter engaged with a stop collar 12 vwhich is fixedly connected to the rod 5. The feet. 10 operate or slide in vertical slots 13 v that are rovi ded therefor in the sides of the coin c utes.

ter with thedesired sum 35 and is held by A vertical lever 14 ispivoted at 15 within the casing and carries fingers 16 intermediating its ends, which fingers project within the coin chutes and are of varying lengths so as to engage the varidiametered coins.

A dog 17 is pivoted at 18 to the lower end of the lever 14 and is tensioned by a coil spring 19. The dog 17 engages the teeth 20 of a toothed wheel 21 the latter being mounted ona shaft 22. A pawl 23 is pivoted to the casing and engages the teeth 20 of the wheel 21 so as to prevent retrograde movement of the wheel.

A second dog 24 is loosely journaled on the shaft22' and has anose 25 formed to engage in an L-shaped cutout or tooth 26 provided in a vendin machine operating shaft 27.

The shaft is provided with an arm 28 which is connected to a coil spring 29 by means of which the dog 24 is normally tensioned to move downwardly. A finger 30 is secured to the shaft 27 in a position so as to engage an in'clined'face 31 formed on the dog 17 upon turning of the shaft, thereby to lift the dog out of engagement with the teeth 20 of wheel 21.

As shown in Figure 1 of the drawing, the a shaft 27 has an operating handle 32 thereon and the shaft 22 is provided with an arm 33 which is formed to engage a set screw 34, 7 the latter being engaged in a selected one of a seriesof openings 35 provided therefor in a side of the casing. These o ening are provided with the indicia 5 10; 15,- 20, 2,5 to indicate various sums of money necessary to deposit in order tooperate the vending machine. Closure 36 is provided for the projecting end of the shaft 22, the arm 33, and the set screw 34, and is locked by means of a lock 37. As shown in Figure 1 the shaft 27 is provided with a stop lug 38 formed to engage a stop pin 39 attached to a side of the caslng.

' In operation, the arm 33 is moved to registhe screw 34, this movement ofv the arm causes the shaft 22 and therewith lug 30 on the wheel 21 to-be set in 'a position according to the amount for which the arm 33 is set. Assuming that the arm 33 is set for cents it will be apparent that the operator must first deposit either 'adime or a nickel -in the slot 4 or 3, whereupon rod 5 is pushed downwardly to cause the coin to engage the finger 16 thereby to rock lever 14 and move dog 17 to rotate the wheel 21. Then the remaining coin is inserted in its proper slot and the rod 5 is again pushed downwardly- 'thereby causing a further movement of the with the teeth 20 of wheel 21'. At this time seen that the shaft 2 the movement of t 7 arm 28 tensions the spring 29 so that ,w en the shaft 27 is released the arts are automaticall restored to the position of'Fi re 4 in whic it will be g is in locked position. Having thus described my invention what I claim as new and desire to secure by Letters Patent is I 1. In a device of the type set forth, a

casing having chutes for coins of varying denominations, spring ressed pusher means for the coins, a lever avi'ng coin-engaging fingers -which latter project within the chutes, a vending machine operating shaft having a notch, a second shaft having a toothed wheel keyed thereto, a spring pressed dog ivoted to said lever and key engagea le with the-teeth of the wheel to turn the latter, a pioted pawl overlying said dog and engaging the wheel to prevent retrograde movement of the wheel, a dog loose on the second shaft and enga cable in said notch ofthe vendin mac ine operating shaft, a finger on t e vending machine operating shaft to operate said spring pressed dog and therethrough said pawlto release the wheel, spring'means connected to the loose dog and to said vending'machine operating shaft to restore the loose dog to normal position following operation of the last named shaft, means to hold said second shaft and thereby the wheel in different set position and a lug on the wheel to engage the loose dog.
